/** A context to provide necessary context used by stored procedure. */
@PublicEvolving
public interface ProcedureContext {

    /** Return the StreamExecutionEnvironment where the procedure is called. */
    StreamExecutionEnvironment getExecutionEnvironment();
}

Note: To avoid exposing to much to early to devs, we only put  StreamExecutionEnvironment to the ProcedureContext currently since it's the most needed for stored procedure. If we find we stored procedure will need other things, we put add it to the ProcedureContext in the future.

then, we propose a new interface Procedure for stored procedure. The stored procedure providers are expected to implement Procedure  to define their own procedure.
